Talents with new mechanics need to be explained

For the longest time talents were simple to understand. +10 fury swipe damage = more damage on fury swipes. +60 arcane orb duration = longer duration on arcane orb. But now we are in 7.07(c), and valve haven't even bothered to explain some of the talents added in that patch in-game. What's cataclysm? What's a "ghost ship fleet"? Does "Waveform attacks targets" actually do anything useful?

My suggestion is a localization change to fix it. Add it to the tooltip of the ability, like an aghs effect, what the new mechanic does. I believe this would be easy to change since aghs already does it, but I could be wrong.
Something definitely needs to be done about some new talents, though.
